Description
Verfahren zur Herstellung von Halogenwasserstofflösungen Es wurde gefunden, daß flüssige N-substituierte Carbonamide von Fettsäuren sehr gut geeignet sind, um Lösungen der Halogenwasserstoffe, und zwar sowohl des Chlorwasserstoffs als auch des Brom-, Jod- oder Fluoizvasserstoffs herzustellen.Process for the preparation of hydrogen halide solutions It has been found that liquid N-substituted carbonamides of fatty acids are very suitable are to solutions of the hydrogen halides, both of the hydrogen chloride as well as the bromine, iodine or fluorine hydrogen.
Im allgemeinen sind solche Amide besonders vorteilhaft, die sich von niederen Fettsäuren mit bis zu 5 Kohlenstoffatomen .ableiten oder in denen die Substituenten ,am Stickstoff niedrigmolekular sind, also z. B. Alkylgruppen mit bis zu 5 Kohl.enstoffatomen darstellen; am besten geeignet sind solche Amide, in denen beide Bedingungen erfüllt sind. Im allgemeinen kann man sagen: daß die ,a.m Stickstoff disubstituierten Amide sich noch günstiger verhalten als die monosubstitui;ert@en. Geeignete Amide sind beispielsweise Monomethylfo!rmamid, Dimethylform,amid, Methyläthylformamid, Mono- und Dipropylformamid, Mono- und Di,allkylformamid, Mono- und Dibutylformamid, Methylacetamid, Mono-oder Dimethylpropionamid, Dimethylstearinamid, Formylpyrrolidin oder auch Gemische dieser Säureamide.In general, those amides which differ from derive lower fatty acids with up to 5 carbon atoms or in which the substituents , are low molecular weight on nitrogen, e.g. B. alkyl groups with up to 5 carbon atoms represent; The most suitable amides are those in which both conditions are met are. In general one can say: that the amides, a.m nitrogen disubstituted behave even more favorably than the monosubstituted @ s. Suitable amides are for example monomethylformamide, dimethylform, amide, methylethylformamide, mono- and dipropylformamide, mono- and di, alkylformamide, mono- and dibutylformamide, methylacetamide, Mono- or dimethylpropionamide, dimethylstearinamide, formylpyrrolidine or mixtures this acid amide.
Beispielsweise vermag das Dimethylformamid bei o° und 76omm Druck mehr als das Eigengewicht an Chlorwasserstoff und etwa das al/Jache des Eigengewichts an Bromwasserstoff zu absorbieten und auch bei Zimmertemperatur noch beträchtliche Mengen dieser,Gase aufzunehmen. Bei Erwärmen und bzw. oder runter vermindertem Druck werden die Halogenwasserstoff e wieder abgegeben, tihne daß die Absiorptionsflüssigkeit dabei wesentlichen Schaden leidet.For example, dimethylformamide is capable of pressure at 0 ° and 76 ° more than its own weight in hydrogen chloride and about the equivalent of its own weight to absorb hydrogen bromide and also at room temperature still take up considerable amounts of these gases. When warming up and / or down The hydrogen halides are released again under reduced pressure, without the Absorbing liquid suffers substantial damage in the process.
Das Verfahren kann beispielsweise dazu dienen, um aus trockenen Gasen, die H,alogenwasserstoffe enthalten, diese zu absiorbieren und nachher wieder in Freiheit zu setzen. Dabei kann unter beliebigen Drucken gearbeitet werden. Bei, erhöhtem Druck und bei tiefer Temperatur ist das Absorptionsvermö;gen,der genannten Amide am besten. Es ist dabei auch günstig, daß die Siedepunkte der Amide ziemlich hoch liegen und ihre Verdunstungsgeschwindigkeiten klein sind, so daß beim Austreiben des Halogenwasserstoffs keime nennenswerten. Mengen Lösungsmittel verlorengehen. Wegen der hohen Halogenwassierstoffkonzentrationen kann man mit den Lösungen auch chemische Reaktionen vornehmen. Beispiel i Man leitet bei o° und unter gewöhnlichem Druck Chlorwasserstoffgas durch eine poröse Platte in i oo g Dimethyliormamid. Es werden etwa i 3 a g, d.h. etwa 831 Chlorwasserstoff absorbiert. Beize Erwärmen joder Evakuieren wird das Gas wieder abgegeben.The method can be used, for example, to convert dry gases, which contain hydrogen atoms, to absorb them and then to reintegrate them Freedom to put. You can work under any pressure. At, increased pressure and at low temperature is the absorption capacity; gen, the mentioned Amide best. It is also favorable that the boiling points of the amides are fairly high are high and their evaporation rates are low, so that when expelled of the hydrogen halide germs worth mentioning. Loss of solvent. Because of the high hydrogen halide concentrations, one can also use the solutions carry out chemical reactions. Example i One leads at o ° and under ordinary Pressurized hydrogen chloride gas through a porous plate in 100 g of dimethyliormamide. It about i 3 a g, i.e. about 831 hydrogen chloride, are absorbed. Stain warming yoder Evacuation releases the gas again.
Beispiel a Man leitet bei o° und unter gewöhnlichem Druck durch eine poröse Platte Bromwasserstoff in ioog Diäthylformamid. Es werden in kurzer Zeit etwa zq.6;g, das sind etwa 681 Bromwasserstoff, absorbiert. Durch Erwärmen läßt sich der Bromwasserstoff wiedergerovinnen. Beispiel 3 Man leitet ein trockenes, Fluorwasserstoff !enthaltendes Gasgemisch bei Temperaturen zwischen o und i o' durch Dimethylacetamid. Der Fluorwass:erstoff wird absorbiert und kann anschließend durch Erwärmen der Lösung rein zurückgewonnen werden.Example a One passes through a at 0 ° and under normal pressure porous plate hydrogen bromide in ioog diethylformamide. It will be in a short time about 6; g, that is about 681 hydrogen bromide, is absorbed. Leaves by heating the hydrogen bromide re-gerovin. Example 3 A dry, Gas mixture containing hydrogen fluoride at temperatures between 0 and 10 ' Dimethylacetamide. The hydrofluoric acid is absorbed and can then pass through Heating the solution can be recovered pure.
